How can I parse String to Int in an Angular expression?
angularjs, javascript
Solution
In your controller:
$scope.num_str = parseInt(num_str, 10); // parseInt with radix
Problem
A number string '5' ``` var num_str = '5'; ``` How can I parseInt and let below answers correct at the same time? ``` {{num_str + 1}} // 6 {{num_str - 1}} // 4 ``` parseInt can't be used in an Angular expression, ``` {{parseInt(num_str) - 1}} ``` number filter can't do add and minus, ``` {{num_str - 1 | number}} ``` If anyone have useful suggestion, I will very appreciate of you
